In Mark Chapter 5, Jesus came across a man who had thousands of demons inside of him. The demons called themselves Legion, due to their number. We also read how only Jesus had the power to deliver the man who was possessed by Legion. The demons were so powerful that not even chains retrained him.
The second part of the Chapter talks about a woman who was bleeding for 12 years was healed by just touching the edge of Jesus’ cloak. Jesus raised a 12-year-old girl from the dead.
